Creates a BinaryExpression that represents raising a number to a power.
public:
static System::Linq::Expressions::BinaryExpression ^ Power(System::Linq::Expressions::Expression ^ left, System::Linq::Expressions::Expression ^ right);
public static System.Linq.Expressions.BinaryExpression Power (System.Linq.Expressions.Expression left, System.Linq.Expressions.Expression right);
static member Power : System.Linq.Expressions.Expression * System.Linq.Expressions.Expression -> System.Linq.Expressions.BinaryExpression
Public Shared Function Power (left As Expression, right As Expression) As BinaryExpression
Parameters
- left
- Expression
An Expression to set the Left property equal to.
- right
- Expression
An Expression to set the Right property equal to.
Returns
A BinaryExpression that has the NodeType property equal to Power and the Left and Right properties set to the specified values.
Exceptions
left
or right
is null
.
The exponentiation operator is not defined for left
.Type and right
.Type.
-or-
left
.Type and/or right
.Type are not Double.
Remarks
The resulting BinaryExpression has the Method property set to the implementing method. The Type property is set to the type of the node. If the node is lifted, the IsLifted and IsLiftedToNull properties are both true
. Otherwise, they are false
. The Conversion property is null
.
The following information describes the implementing method, the node type, and whether a node is lifted.
Implementing Method
The following rules determine the implementing method for the operation:
If the Type property of either
left
orright
represents a user-defined type that overloads the exponentiation operator, the MethodInfo that represents that method is the implementing method.Otherwise, if
left
.Type andright
.Type are both Double, the implementing method is Pow.
Node Type and Lifted versus Non-Lifted
If
left
.Type andright
.Type are assignable to the corresponding argument types of the implementing method, the node is not lifted. The type of the node is the return type of the implementing method.If the following two conditions are satisfied, the node is lifted and the type of the node is the nullable type that corresponds to the return type of the implementing method:
left
.Type andright
.Type are both value types of which at least one is nullable and the corresponding non-nullable types are equal to the corresponding argument types of the implementing method.The return type of the implementing method is a non-nullable value type.
